I am 99% sure not. You have to have a Pokemon native to the language the game is played on, and a Pokemon from a foreign language cartridge/save file.

E.g.:
• A Spanish Skitty and a Spanish Wailord on a English game: NO
• A Spanish Skitty and a English Wailord on a Japanese game: NO
• A Japanese Skitty and a Japanese Wailord on a Japanese game: NO
• A Spanish Skitty and a English Wailord on an English game: YES
